[Rpcemu] Revised Mac patch for 0.9.2

Hello all

Please find attached a revised Mac patch that implements keyboard and network support in RPCEmu. This incorporates a fix for the loading of the 'netroms/EtherRPCEm,ffa' file that was kindly contributed by David Pitt.

You should unpack the ZIP file in the "rpcemu-0.9.2/src" folder and apply the patch from there, i.e.:

patch -p0 -i ./rpcemu-0.9.2-mac-patch-v3.diff

The patch should successfully apply without error. Next, change into the "qt5" folder, and type the following:

qmake
make -j4

(Increase the 4 to however many cores you've got.)

This should produce an "rpcemu-interpreter.app" application in the top-level "rpcemu-0.9.2" folder. Double-click to run in the normal way.

As ever, comments and bug reports are welcome.

Tim
